Failure Date: 02/12/2022

The vehicle's automatic stop-start feature malfunctioned and shut the engine off while I was driving with my 3 children in the car. Our safety was at risk because the car shut off in the middle of the road and we had to wait for an hour for the tow truck to come and give us a jump. There was no prior warning before the car shut off. Afterwards the message "high power consumption partial limit on ac/heater operation" came on I was very nervous for my kids and I safety.

38 Engine And Engine Cooling problem

Failure Date: 11/29/2021

Recently purchased this Highlander on August 2021. On 11/29/21 at around 8:00 am, the check engine light illuminated resting stop at a red light. Engine still running. Took the vehicle to the dealership at 9:45am. Vehicle was found to have had misfires as a result of bad gasoline. I have been pumping at the same gas station ever since I bought the vehicle. If it was the bad gas, this issue should have happened sooner. Now, the dealership is telling me to pay for the diagnostic fee which they claimed it was my fault. The vehicle is under warranty. Another non-power/fuel issue that came with the vehicle was a loud wind noise when reaching 40 mph. The noise is very annoying, like someone whistling into your ear. The dealership is ordering a part to fix this issue. The vehicle is still at the dealership.

41 Engine And Engine Cooling problem

Failure Date: 05/13/2021

Upon attempting to engage the brakes, it was found that they did not work. Immediately thereafter, the car began an uncommanded full acceleration. The insurance company has totaled the car. Our safety as occupants was obviously at serious risk. The driver chose to take the car off the road rather than jeopardize the lives of others on the same road. The car plowed through boulders and trees, coming to rest upside down wedged between an earthen berm and a tree. . . . . . Suspended about 2 feet above the ground. There were no warnings prior to the incident. The car has been inspected by the insurance company, and has been authorized for inspection by the manufacturer. There were no serious injuries as a result of the accident. We were very lucky! uncommanded acceleration without any control is a frightening event any time. . . . But definitely in the vicinity of other vehicles full of families.
